Universal Gravitational Constant
The universal gravitational constant, abbreviated as G, (also called gravitational constant, Newton constant of gravitational, and Cavendish gravitational constant), is the proportionality constant used in Newton's Law of Universal Gravitation. This constant is very difficult to measure with any high accuracy.
